MITRE ATT&CK

The file is identified as an antivirus bait by its content and ClamAV detections. The presence of an Auto_Open macro indicates an attempt to execute code upon opening the Excel file, a common technique for malware delivery. However, the primary purpose appears to be triggering antivirus detection rather than performing a malicious action.
